I have a desktop computer running Debian Buster Mate that I want to move
to a different location and use Wifi.
Using a cheap USB dongle NetworkManager Applet detects the device, lets
me select from available networks, accepts password, but will not
connect..and after a few moments it closes..
Thinking the drivers were not installed (user error) I tried a fresh Net
install alongside.
firmware-10.1.0-amd64-netinst.iso
I unplugged the ethernet cable was unplugged, the installer detected the
USB device, install worked as expected.
First boot, again the device is detected with NetworkManager Applet, but
same thing... will not connect and after a few moments it closes.
I also tried Buster Mate Live.
debian-live-10.1.0-amd64-mate+nonfree.iso
D-I installer works but the result is the same as the Net installer.
device detected, but will not connect.
Running a Live session device detected, but will not connect.
Ubuntu Mate works, Linux Mint Mate works.
... I am at a loss of where to begin.

meter away and it has the same problem
